We left Play Encanto at 7:30 Tuesday morning. Arrived at the San Luis Border via Highway 2 at 10:00. , correction 10:30 ..We were in the general lane < middle lane > with passports only. 2.5 hours later we crossed into San Luis Az. I asked the gal at the stop what would happen if we would’ve took the ready lane on the right hand side, she said we would immediately be sent to secondary. With a smile as you might be there a long time….. FYI at San Luis in case you didn’t know, which we didn’t. right hand lane is the ready lane, enhanced drivers license, passport card, etc. Middle lane is passport only, left-hand lane on the left of the yellow concrete barrier is the Sentri Lane
